Abstract
A blood sampling device is provided with a housing, a lancet assembly, a lancet holder which is movable in a lancing direction between a cocked position and a puncture position, and an actuator mechanism disposed in the housing for causing the lancet holder to move from the cocked position to the puncture position. The lancet assembly has a lancet with a sharp tip, a lancet body having at least two angularly spaced ribs which extend outwardly from a central portion of the lancet body, and a protective cap covering the sharp tip of the lancet, the protective cap being attached to the lancet body so that the protective cap is twistably removable from the lancet body. The lancet holder has an aperture formed therein, the aperture having a cylindrical shape and being substantially unobstructed so that the lancet body may be inserted into the aperture in any angular orientation relative to the lancet holder, and the blood sampling device includes a mechanism for preventing significant rotational movement of the lancet body relative to the lancet holder when the lancet body is disposed in the aperture formed in the lancet holder and when the protective cap is subject to an angular force …
